3 main functions of skeletal system (sat morning mumps - MPS)
movement, protection and storage of minerals and fats
functions of bones (think milk)
synthesize blood and immune cells, store calcium phosphate and lipids
4 major types of bones
long, short, flat, and irregular
ex. of long bone
femur
marrow in a long bone (long yellow)
yellow marrow that stores lipids
found at the end of long bones
red marrow, site of blood cell production
growth plates
at the ends of long bones, where bone lengthens if it’s growing
ex of short bones
square bones of wrists and ankles
ex of flat bones and their function
protect vital organs - ribs
flat bones contain…
red bone marrow and produce blood cells
ex. of irregular bones
hips and parts of skull
ligaments (leg to leg - bone to bone)
attach bones to other bones
only bone in body not connected to other bones
hyoid-held only by muscle
hyaline cartilage
covers articulating surface of bones so they don’t grind together
ex. of synovial joints (balling is a sin)
ball and socket, hinge - usually capable of movement. knee hinges, have synovial fluid
